The Storm

S1 E10: The team learns that a storm of catastrophic proportions is headed straight for the city of Atlantis. Without enough energy to power the shields Dr. Weir (Torri Higginson) orders that Atlantis be evacuated until the storm passes. But Dr. McKay (David Hewlett) conceives of a last minute plan to save the city--harness the power of the electrical storm to fuel the shields. Meanwhile unbeknownst to the Atlantis team the Genii have learned of AtlantisΓÇÖ evacuation and devise a dangerous plan to take over the cityΓÇÖs weapons for themselves. With Weir and McKay taken hostage and Lt. Ford (Rainbow Sun Francks) and Teyla (Rachel Luttrell) aiding the evacuees it is up to Major Sheppard (Joe Flanigan) to shut down the remaining grounding stations and save Atlantis from invasion before the storm hits.
